The Evolution of Folder Icons in macOS Big Sur

In macOS Big Sur, Apple has introduced a new design language for folder icons that is both visually striking and functional. Designed in conjunction with the San Francisco font, these icons are intended to blend seamlessly into the user interface, providing a cohesive look across all applications.

One of the most notable changes is the adoption of rounded shapes, which replaces the traditional angular designs found in previous versions of macOS. This shift towards more curved lines gives the icons a softer, more approachable feel that is reminiscent of iOS design principles.

Another significant departure from classic Mac interface design is the removal of gradients and shadows. While these elements can add depth and visual interest to an icon, they have been replaced with bold, flat colors that allow the icons to stand out on their own merit.

In my opinion, these new folder icons don't quite work well within the macOS ecosystem, and I think it's best to avoid this iOS-inspired style. However, Apple has also introduced a range of other apps that adopt this new design language, including Xcode, Sticky Notes, System Preferences, and Messages. These apps showcase how the new icon design can be used effectively in different contexts.

One of the unique aspects of these new icons is their ability to incorporate elements that float above the basic shape layer. For example, the Xcode icon features a hammer floating above a blueprint, adding an element of depth and visual interest to the design.

In terms of how these icons are structured, they can be divided into two main categories: those that fit within a squircle (a square with rounded corners) and those that feature elements that float above this basic shape layer. While iOS icons tend to be flat and masked to a squircle, traditional Mac icons have historically featured more depth and varied in terms of shape and design.

With the release of macOS Big Sur, every icon in the operating system has been redesigned to fit within this new framework. This goal was achieved by redesigning the entire user interface to resemble iOS, with Apple's chief human interface designer Alan Dye describing the aim as bringing more clarity to the Mac.

While it's understandable that some users may be hesitant about these changes, I believe that the new design language has the potential to breathe fresh life into the Mac interface. By adopting a more modern and streamlined approach, Apple is providing users with a cohesive and visually appealing experience that sets the stage for future innovations in macOS.
